To all whom it mag/,concern Be it knownthat I, DANiEL M. WATSON, ar

citizen of the United States, residing at Portland, in the county` of `,Multnomah and State of Oregon,'liave invented certainnew and useful Improvements in Pumps, of which the following is a specification.

Thisinvention has reference tofnpumps and its object is -to provide apump in which no iiuid'passes through the working barrel, 'but is kdirected wholly about the working Theinvention comprises a pump casing in which there is mounted a i4working barrel freely open at the oppositeV ends andthere supported' by spacing members lodged in fthe casing with one of thefs'pacing niembers" serving as a valve seat -and having a valve structure associated therewith. The other spacing member is so constructed that the valve structure'may be associated'withV lit after being removedffrom the first spacing member, sothat in the event of wearA the `working barrel may be reversed Vin position, Athereby prolonging the life of the pump.

Associated with the working barrel is a pumpy plunger having packing means ar- A'ranged for self packing andy also arranged for *taking up wear without the necessity ofthe removal of the .plunger fromy the workin barrel.` v ,Y f f The invention will loe best understood from a consideration of the followingdetailed description, taken in connection with the accompanying drawings forming part of this specification,` with the further, understanding that while'rthe drawings" show a practical form of the invention; thelatter is not confined to any strict conformity with the showing of the drawings,but may be changedl and kmodified Vso long-as f such changes and modications come within the In the drawings Figure 1 is an elevation yof the pump'.

.Referringto the drawings there is shown l" a pump casing 11 of suitable length and di 'ameter connected at the ends'bycouplings 2, 3,V respectively,"to respective reducers 4, 5.

The reducer 4' is conectedby a coupling- 6 to a pipe 7 which maybe assumed to lead to -v f The reducer 5 is connected to a 13 with its seat 14, and connectedto the coupling 11 is a strainer 15 which'may be 'of ordinary construction `and hence needs no special description. .The two check valves 9 and `1??)constitute footvalves, while the nip'- ple 12 may be replaced by any appropriate -length of pipe separating the two valves 9 Y and 13 to a'greater extent than indicated in the drawings. 'I y 1 Within the coupling 3 there is lodged a 'spacer lring 16 `interiorly threaded forthe reception of one end of the workingbarrel 17 of 'considerably less diameter'thanjthe Y casing land ofgreater lengththanl the cas-A fi'ng 1, sot-hat one end 18 lof the loarr'ell'? may'extend -through and beyond the ring f 16""and the other` end 19 of the workingba'r rel may extend through and beyond vanother spacing ring` 20 similar to thering 16 "and Vlodged in the coupling' 2` The I rings 16 and 20 are clamped between correspondingendsi `of the pump casing'l andtherespective re'- d'ucers 5 ande. f i 'I l Screwed on tothe threaded end-19 ofthe barrelh'l? isa ball cage'21 confining hall vvalves 22`to the ring 2Ok in operative relation to passages 23 through the ring, the balls 22 seating atpthos'e ends-of the pas- 'sa'ges- 20 toward the case 21. Pockets 21 fare' formed in the 'cage 21 to receive the balls 22 and the ends'ofy the pockets remote from those receivingthe'balls open through the cage by way of passages 25,'so that the balls may `move freely toward and from thefpas-V sages 23 to closeandlopen them. `'.lhe-cage 21 is small enough in diameter/to have its peripheral Vportion spaced from the inner wall of the reducer i,jso that water passving through the lvalve structure has ample 'rojoin to movealoout the cage into the repassages` Vtherethrough corresponding to V for the passages 26;

When the plunger is lowered into the well the hollow pump rod fills with water up to the plug 42 and when the plunger is pulled from the well, the contained water drains out through the perforation 41, the perforation 43 acting as a vent in either case The pump rod lfL may be made of sections of suitable length joined together by couplings 44.

rlhe pump is particularly useful in deep wells and especially for pumping oil where sand or grit or silt is present. Under such conditions, when the pump is at rest, sand or the like, which is held in suspension in the oil, deposits upon the valves. In such deep well lpumps, it is the custom to cause the thereon and down stroke of the piston solely by gravity because of the impracticability of applying force to cause the down stroke toa pump rod many hundreds of feet in length. When the valves are located at or close to the lower end of the pump barrel, a gravitating pump plunger lacks the necessary power to 'slodge the sand, and therefore, if the deposit of sand be relatively heavy, the pump must be withdrawn from the well in order to clean out the deposited sand. This is necessarily a time consuming and expensive procedure, and is not to be tolerated if it occurs frequently.

By extending the pump plunger above the upper end of the working barrel to a distance which will maintain it alfways -above the upper end of the working barrel, and by locating the valves close to the upper end of the working barrel, any deposits of sand on the upper valves are subject to violent agitation due to the movements of the pump plunger. Consequently, a few strokes of the pump plunger dislodge all accumulated sand, thus avoiding any necessity of pulling the pump for cleansing purposes.

What is claimed is l. A pump comprising a pump casing, a

working barrel within the pump casing, a

displacement plungerfor the working barrel, spacing means at the opposite ends of the working barrel for centralizing the latter in the pump casing, and valve members associated witlnone of the spacing means, said spacing means being of like construction for the association of the valve means with either spacing member.

2. A pump comprising a casing, a working barrel freely open at the opposite ends with each end exteriorly screw threaded, a spacing ring at each end of the barrel threaded provided with passages therethrough exterior to the barrel, a valveV cage Copies ofthis patent may be obtained for five cents each, `by addressing the and valve members applied to one end ofk ger for the barrel having a stroke carrying its lower end below the working barrel, sai plunger having packing at its lower end, and the casing below the barrel and the lower end of the plunger having coperating means for taking up wear in the packing, comprising a screw on the lower end of the plunger and 'a fixed member extending transversely of the casing to engage the screw and actuate it by rotative movements of the plunger.

4. A deep well pump comprising an upright casing, an open-ended working barrel within the casing, a'reciprocatory displacement plunger located in the barrel and provided with packing at its lower end, a headed screw eXtending through the packing and a fixed member in the casing for engaging the head of 'the screw, said fixed member being located at a lower point than the normal downward stroke of the plunger, to be engaged by the screw for causing the latter to compress the packing when the plu-ngerfisv lowered beyond its normal lowermost limit and is rotated.

5. A pump comprisin a casing, an open ended working barrel t erein, a displacement plunger for the working barrel, like spacer rings at opposite ends of the working ing barrel therein with eXteriorly screwthreaded ends, a displacement plunger for the working barrel, like spacer rings on the threaded ends of the working barrel with each spacer ring having passagesl therethrough, and a valve structure applied to f one threaded end of the working barrel and adapted to either end and located in operative relation to Lthe passages through the spacer ring with which it is associated.

In testimony whereof I afli-X my signature in the presence of ltwo witnesses.
